After almost a week, the person who bought a $25-million winning Lotto Max ticket in the Ottawa-area still hasn't claimed the prize.

The unclaimed money has many dreaming of what they would do with that amount of cash. Some would buy fancy cars, others would put the winnings in the stock market, go on a trip or invest in real estate.

In Ottawa, the most expensive house on the market is a luxury home in Rockcliffe, listed at almost $7 million -- only a fraction of the winnings.

"In Rockcliffe Park, in Canada, in the national capital, you couldn't find a better property to buy," said Christopher Barker, of Coldwell Banker Rhodes Brokerage.

The property is designed by world-renowned landscape architect Ron Holbrook, and is one of a kind: "They incorporated an Oak leaf conservatory that was brought over from England, and in addition, they imported some 200 trees and landscaped the entire lot," Barker said.

Prioritize, then spend

Although there are lots of things you can buy with $25 million, financial advisors say making a priority list is step one.

"You can go through 25 million dollars fairly quickly actually," said Susan St. Amand, of Sirius Financial Services.

She says although many people dream of winning millions, it can also cause a lot of unwanted stress.

"Finances can cause divorce and all kinds of family havoc (when you're in debt); the same kind of thing can happen when you all of a sudden come into money because the dynamics have completely changed," she said.

Checking your numbers

Although the winning ticket has not yet been claimed, many have checked their ticket twice. Even Ontario's premier checked his pockets: "I have too many damn brothers and sisters, and 20 nieces and nephews . . . I'd go broke very quickly," Dalton McGuinty told CTV Ottawa on Thursday.

Last week's $50-million jackpot was split between a winner in the Ottawa-area, and a winner in Quebec.

Every year, there are unclaimed lottery prizes. In Ontario, the government keeps tabs on unclaimed prizes that don't belong to national lotteries such as Lotto Max and Lotto 6/49.

After one year, if nobody claims the money, the government takes ownership of the cash.
